kandi X-RAY | queen Summary

queen is a JavaScript library typically used in Server, Runtime Evironment, Nodejs applications. queen has no vulnerabilities and it has low support. However queen has 1 bugs and it has a Non-SPDX License. You can download it from GitHub.

Queen is a server which is capable of brokering socketed communication between browsers which are connected to it and other applications or scripts. You can think of the Queen Server as a pool of browsers which you can execute code on. Taking the abstraction further, you can think of Queen Server as distributed execution platform using browsers as computation nodes. Let's say you want to play a "game" where you write down a number and others try to guess it. You gather some friends and tell them to start giving numbers at you. Your friends keep giving you random numbers until one of them gets it right. Now imagine your friends are browsers, and the game is a script which tells browsers how to play, and waits for the right number to be guessed. This makes you the Queen Server. The Queen Servers allows you to perform distributed tasks on many browsers -- a platform for running scripts on many browsers.

Multiple table joins in Oracle SQL with same column names

Asked 2021-Jun-15 at 22:43

Currently I have 3 tables like below

Master

ID_NUMBER ZIPCODE 1 12341 2 12342 3 12343 4 12344

Table1

ID_NUMBER CITYNAME COUNTYNAME 1 NEW YORK QUEENS 3 DETROIT SUFFOLK

Table2

ID_NUMBER CITYNAME COUNTYNAME 2 ATLANTA ROCKLAND 4 BOSTON WINCHESTER

My desired output is like below. I want to filter based on the zipcode from master table

ID_NUMBER ZIPCODE CITYNAME COUNTYNAME 2 12342 ATLANTA ROCKLAND

How would i go about writing a query for this? Below is what i have tried but it's giving me null values if the ID_NUMBER is not found on that particular table.

How to remove mutability from this function in scheme (N-queens)

Asked 2021-Jun-12 at 19:59

I'm arduously struggling my way through the N-queens problem in SICP (the book; I spent a few days on it -- last question here: Solving Eight-queens in scheme). Here is what I have for the helper functions:

...

ANSWER

Answered 2021-Jun-12 at 09:35

When you are doing the SICP problems, it would be most beneficial if you strive to adhere to the spirit of the question. You can determine the spirit from the context: the topics covered till the point you are in the book, any helper code given, the terminology used etc. Specifically, avoid using parts of the scheme language that have not yet been introduced; the focus is not on whether you can solve the problem, it is on how you solve it. If you have been provided helper code, try to use it to the extent you can.

SICP has a way of building complexity; it does not introduce a concept unless it has presented enough motivation and justification for it. The underlying theme of the book is simplification through abstraction, and in this particular section you are introduced to various higher order procedures -- abstractions like accumulate, map, filter, flatmap which operate on sequences/lists, to make your code more structured, compact and ultimately easier to reason about.

As illustrated in the opening of this section, you could very well avoid the use of such higher programming constructs and still have programs that run fine, but their (liberal) use results in more structured, readable, top-down style code. It draws parallels from the design of signal processing systems, and shows how we can take inspiration from it to add structure to our code: using procedures like map, filter etc. compartmentalize our code's logic, not only making it look more hygienic but also more comprehensible.

If you prematurely use techniques which don't come until later in the book, you will be missing out on many key learnings which the authors intend for you from the present section. You need to shed the urge to think in an imperative way. Using set! is not a good way to do things in scheme, until it is. SICP forces you down a 'difficult' path by making you think in a functional manner for a reason -- it is for making your thinking (and code) elegant and 'clean'.

Just imagine how much more difficult it would be to reason about code which generates a tree recursive process, wherein each (child) function call is mutating the parameters of the function. Also, as I mentioned in the comments, assignment places additional burden upon the programmers (and on those who read their code) by making the order of the expressions have a bearing on the results of the computation, so it is harder to verify that the code does what is intended.

Edit: I just wanted to add a couple of points which I feel would add a bit more insight:

Your code using set! is not wrong (or even very inelegant), it is just that in doing so, you are being very explicit in telling what you are doing. Iteration also reduces the elegance a bit in addition to being bottom up -- it is generally harder to think bottom up.
I feel that teaching to do things recursively where possible is one of the aims of the book. You will find that recursion is a crucial technique, the use of which is inevitable throughout the book. For instance, in chapter 4, you will be writing evaluators (interpreters) where the authors evaluate the expressions recursively. Even much earlier, in section 2.3, there is the symbolic differentiation problem which is also an exercise in recursive evaluation of expressions. So even though you solved the problem imperatively (using set!, begin) and bottom-up iteration the first time, it is not the right way, as far as the problem statement is concerned.

Having said all this, here is my code for this problem (for all the structure and readability imparted by FP, comments are still indispensable):

QUESTION

Query to Find Adjacent Records in Access 2016

Asked 2021-Jun-11 at 08:36

I have a table with a field called Result that contains values that can be anywhere between 1 and 100.

The table also contains a Date/Time field and is sorted from oldest to newest.

I want to be able to return adjacent records that have a Result of less than 3.

So, I need to first find a record with a Result that is less than 3 then check if the next records also have a Result of less than 3. If they do these records should be returned.

There may be no such adjacent records or there may be multiple records that meet this criteria.

Is this possible?

I've put together a short piece of code that loops the original data, ordered by the date field, and if it finds a result of less than 3, checks the following results until one of them is 3 or more. It adds all of the ID fields to a string, which can then be used as the SQL for a query.

Axios.get returns status code 400 cant figure out whats wrong (SODAapi)

Cant figure whats wrong with my axios call. Any help would be much appreciated.

So I have a search bar onClick that will send search terms to a function that compile the Api query string.

ANSWER

Answered 2021-Jun-11 at 03:18

The % characters in your query string aren't being encoded properly. They should be encoded as %25. See https://developers.google.com/maps/documentation/urls/url-encoding

The easiest way to ensure this with Axios is to use the params config. Any keys / values in there will be URL encoded.

There are many ways to solve this problem. For starters, I'd suggest a simpler representation for the board, I chose to use a list of numbers. The indexes in the list start from one and indicate the queen's column and the value its row (origin of coordinates is on the upper-left corner, new positions are adjoined at the end of the list); all the other positions are assumed to be empty. For instance, the following board:

Basically I am making a Web implementation of Jacks or Better: Video Poker. For some reason I keep getting my kings queen jacks and tens are recognized as the same value.
